Placental chorangioma
Abstract
Placental chorangioma is a rare tumor with a frequency of 1%. It presents as a solitary nodule or less frequently as multiple nodules on the fetal surface of the placenta or within the placental parenchyma. Placental chorangiomas are considered clinically significant when >4 cm. Fetal complications associated with placental chorangiomas include polyhydromnios, nonimmune fetal hydrops, fetal heart failure, cardiomegaly, intrauterine growth restriction, fetal anemia, thrombocytopenia, and fetal demise. Maternal complications such as preeclampsia, preterm delivery, and maternal mirror syndrome are also associated with placental chorangiomas. The pathophysiology behind the complications is yet to be fully elucidated, but a prominent role for arteriovenous shunting and sequestration of red blood cells and platelets by the chorangioma has been postulated. The case presented was a 20‑year‑old primipara at 36 weeks of gestation with live fetus and an incidental finding of mixed echogenic mass lesion within the placenta measuring 59 mm × 52 mm. She was planned for elective cesarean section but went into spontaneous labor and had uneventful vaginal delivery.
